Abstract
A cutout (4) is made in a room wall (2) and flexible tubing (13) connected to a vacuum conduit (12) is pulled therethrough. A box (1) is attached to the tubing and includes a frame portion (15) for surrounding the cutout, and inwardly recessed portion (18) having side and top and bottom walls (19-22) and a back wall (23), and outwardly and inwardly extending annular connector flanges (25, 26) for connecting to the vacuum wand and the conduit flexible tubing. After the conduit tubing and box are connected, the box is pushed inwardly so that its recessed portion extends through the cutout into the wall. A slot (29, 30) is provided in each vertical sidewall of the box with the slot extending into the back wall so that it is generally L-shaped in section. A generally Z-shaped clip (33) having a long leg (35) and short leg (34) joined by a web (36) is provided for each slot. The short leg is inserted through a slot so that the short leg engages the rear wall face, the web extends forwardly along the side wall of the recess, and the long leg extends across the recess toward the outwardly extending annular flange. The clips make it possible to accommodate various wall thicknesses and cannot fall into the wall during installation. Subsequently, screws are utilized to fixedly mount the box to the wall. A door (27) is pivotally mounted to the box to cover the interior thereof when the box is not in use. The door seals against the outer edge of the outwardly extending flange to prevent air leakage when the system is being used in other rooms. The door is formed (44) for easy engagement and manipulation by the user'"'"'s hose.
